RegionInfo Class
Updated: September 2011
Contains information about the country/region.
Assembly: mscorlib (in mscorlib.dll)
In contrast to CultureInfo, RegionInfo does not represent preferences of the user and does not depend on the user's language or culture.
The RegionInfo name is one of the two-letter codes defined in ISO 3166 for country/region. Case is not significant. The Name, TwoLetterISORegionName, and ThreeLetterISORegionName properties retrieve the appropriate codes in uppercase.
The following is a list of the predefined RegionInfo names accepted and used by this class and other classes in the System.Globalization namespace.

When possible, you should use specific culture names -- for example, en-US for English (United States) -- when you instantiate a RegionInfo object. You can use just a country/region name, such as "US", in the class constructor. However, this technique does not always yield appropriate results. The RegionInfo properties, for instance, DisplayName, depend on culture names for both the language and the country/region. Here are some scenarios in which you should use culture names instead of just country/region names:
When the language name is of primary importance. For example, for the "es-US" culture name on Windows Vista, an application probably requires a display name of "Estados Unidos" instead of "United States". Therefore it needs to work with the culture name instead of the country/region name alone, which yields "United States" regardless of the language.
When script differences must be considered. For example, the country/region "AZ" deals with Azerbaijani cultures having the names az-Latn-AZ and az-Cyrl-AZ, and the Latin and Cyrillic scripts can be very different for this country/region.
When maintenance of detail is important. For a specific culture such as English (United States, named "en-US", your application can lose important information if it tries to create a new RegionInfo object from just the neutral culture name "en" or the country/region name "US".
The following code example demonstrates several members of the RegionInfo class.
Imports System Imports System.Globalization Public Class SamplesRegionInfo Public Shared Sub Main() ' Displays the property values of the RegionInfo for "US". Dim myRI1 As New RegionInfo("US") Console.WriteLine(" Name: {0}", myRI1.Name) Console.WriteLine(" DisplayName: {0}", myRI1.DisplayName) Console.WriteLine(" EnglishName: {0}", myRI1.EnglishName) Console.WriteLine(" IsMetric: {0}", myRI1.IsMetric) Console.WriteLine(" ThreeLetterISORegionName: {0}", myRI1.ThreeLetterISORegionName) Console.WriteLine(" ThreeLetterWindowsRegionName: {0}", myRI1.ThreeLetterWindowsRegionName) Console.WriteLine(" TwoLetterISORegionName: {0}", myRI1.TwoLetterISORegionName) Console.WriteLine(" CurrencySymbol: {0}", myRI1.CurrencySymbol) Console.WriteLine(" ISOCurrencySymbol: {0}", myRI1.ISOCurrencySymbol) Console.WriteLine() ' Compares the RegionInfo above with another RegionInfo created using CultureInfo. Dim myRI2 As New RegionInfo(New CultureInfo("en-US", False).LCID) If myRI1.Equals(myRI2) Then Console.WriteLine("The two RegionInfo instances are equal.") Else Console.WriteLine("The two RegionInfo instances are NOT equal.") End If End Sub 'Main End Class 'SamplesRegionInfo 'This code produces the following output. ' ' Name: US ' DisplayName: United States ' EnglishName: United States ' IsMetric: False ' ThreeLetterISORegionName: USA ' ThreeLetterWindowsRegionName: USA ' TwoLetterISORegionName: US ' CurrencySymbol: $ ' ISOCurrencySymbol: USD ' 'The two RegionInfo instances are equal.
